IMPROVEMENT IN HORSESHO ES. r

Specification forming part of Letters Patent No. 198,824, dated January1, 1878; application filed December 3, 1877.

To all whom it may concemu Be it known that I, EDWIN L. TEvIs, of thecity and county of Philadelphia and State of Pennsylvania, have inventedcertain Improvements in Horseshoes, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, and the letters of reference marked thereon, making part ofthis specification, in which- E Figure 1 is a bottom-plan view. Fig. 2is a longitudinal sectional view on the line as a", Fig. 1. Fig. 3 showsdetached views of the toecalk; Fig. 4, detached views of the heel-calks.

The nature of my invention consists in constructing the toe-calk with acurved flange at its rear section, which laps over and fits the insidearch of the shoe, and a faceplate, which will provide a close fitbetween its inside face and the front of the toe of the shoe, both theface-plate and shoe being provided with grooves, which register whenbrought together, the calk being held in position by means of a commonshoe-nail or wedge, which is driven and rests in the grooves.

My invention further consists in constructinglthe heel-calks with atenon, which fits in a mortise made in the shoe, and a face-plate, whichfits closely to the face of the heels of the shoe. Both the face-platesand these calks are provided with grooves, which register when broughttogether, the calks being held in position by means of a common shoe-nail or wedge, which is driven and rests in the grooves.

The construction and operation of my invention are as follows:

Ais the shoe, which is formed with a groove,

1 a, at the toe, and grooves a a and mortises a a at the heels. B is thetoe-calk, which is provided at its rear with a curved flange, B

and face-plate B as clearly shown in Figs. 2 and 3. The curved flange Bfits the inside archof the shoe, extending around and embracing the topof the same, while the faceplate B closely fits the front of the toeofthe shoe.

For convenience in readily attaching and removing the'toe-calk,thefiange B is curved from the point b to the point W, as shown in Figs.2 and 3, the inside wall of the shoe being also curved to fit the same,as clearly shown in Fig. 2.

The face-plate B is provided with a groove, b, which registers with thegroove a when the calk is attached to the shoe, said calk being held inposition by means of the nail d.

To attach the toe-calk, the flange B is passed up" around the inner wallof the shoe until the flat section b of the flange rests on the upperface of the shoe. The face-plate B is then pushed up, its inner face andthe outer wall of the shoe forming a tight 3' oint. The grooves abhaving registered, the nail d is driven in and clinched, and the calkissecurely fastened.

To remove the calk the nail is driven out, when the calk will partiallyfall by its own weight.

The face-plates G O closely fit the front of the heels-of the shoe, andare provided with grooves c c. When the calks O G are attached to theshoe the tenons G (1 enter the mortises a a while the grooves a aregister with the grooves c c, the calks being held in position by meansof the nails d d.

To attach the calks, the tenons C C are inserted in the 'mortises a aand the faceplates 0 .0 are caused to form a tight joint with the frontof the heels of the shoe. This causes the grooves a a and c c' toregister, when the nails d d are driven in and clinched.

To remove the calks the nails are driven out.

Both the toe-calk and the heel-calks are constructed out of one piece ofmetal.

, These nailsareheldinpositionbytheirpoints being bent over or clinched,and can easily be removed by a hammer and ordinary nail-punch or nail.

I claim as new and desire to secure by Letters Patent of the UnitedStates- 1. A horseshoe, A, provided with a groove, a, the toe-calk B,constructed out of one piece of metal, and provided with a curvedflange, B formed as shown, and face-plate B the latter being providedwith a groove, 1), and

nail d, the whole constructed, combined, and

(1, the "whole constructed, combined, and arranged to operatesubstantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of November, 1877.
